想创建一个用户可以注册一个站点然后他们可以登录的登录。我是要在phpmyadim中添加数据的细节，用户登录我希望从数据库获得详细信息。我已经知道如何做到这一点，但我想知道的是，我怎么知道当用户登录时会将它们带回主页，而右手则表示“hello emma”（或任何已登录的用户）用php和html创建一个登录页面
这里是我的代码
登录
?php
\t //Start session
\t session_start(); \t
\t //Unset the variables stored in session
\t unset($_SESSION['SESS_MEMBER_ID']);
\t unset($_SESSION['SESS_FIRST_NAME']);
\t unset($_SESSION['SESS_LAST_NAME']);
?>
<form name="loginform" action="mylogin.php" method="post">
<table width="309" border="0" align="center" cellpadding="2" cellspacing="5">
<tr>
<td colspan="2">
\t \t <!--the code bellow is used to display the message of the input validation-->
\t \t <?php
\t \t \t if(isset($_SESSION['ERRMSG_ARR']) && is_array($_SESSION['ERRMSG_ARR']) && count($_SESSION['ERRMSG_ARR']) >0) {
\t \t \t echo '<ul class="err">';
\t \t \t foreach($_SESSION['ERRMSG_ARR'] as $msg) {
\t \t \t \t echo '<li>',$msg,'</li>';
\t \t \t \t }
\t \t \t echo '</ul>';
\t \t \t unset($_SESSION['ERRMSG_ARR']);
\t \t \t }
\t \t ?>
\t </td>
</tr>
<tr>
<td width="116"><div align="right">Username</div></td>
<td width="177"><input name="username" type="text" /></td>
</tr>
<tr>
<td><div align="right">Password</div></td>
<td><input name="password" type="password" /></td>
</tr>
<tr>
<td><div align="right"></div></td>
<td><input name="" type="submit" value="login" /></td>
</tr>
</table>
</form>检查登录
<?php
\t //Start session
\t session_start();
\t //Check whether the session variable SESS_MEMBER_ID is present or not
\t if(!isset($_SESSION['SESS_MEMBER_ID']) || (trim($_SESSION['SESS_MEMBER_ID']) == '')) {
\t \t header("location: myindex.php");
\t \t exit();
\t }
?>我的主页

是您的“检查登录”脚本就像你指定的，或者是更长？请添加您用于登录用户的完整代码。如果你只使用它，那么课程用户不会得到验证。 – Eda190 2015-03-13 16:52:15
这就是我所有的代码 – beckyboo 2015-03-13 16:52:49
我似乎无法找到有关您的数据库结构的任何信息。没有这些，我无法回答你的问题，因为要登录一个用户，你必须将他/她输入的数据与数据库中的数据进行比较。 – Eda190 2015-03-13 16:54:37
